This book explains the properties for each type of spring, plus essential materials and methods. Few mechanical devices are entirely devoid of springs of one sort or another, but satisfactory operation rests on details such as spring strength and degree of movement. Yet information on calculating and making springs is not easily available. Designing springs can be difficult due to the number of variables and the complexity of the formula. The book also introduces the designer to charts and nomograms, which greatly simplify the process. Topics include tension and compression spring principles, compression and spring design, examples for winding coil springs, how to design, make, and coil a leaf spring, torsion spring, and I.C. engine valve springs.Show book
In the 1880s, Freud discovered cocaine and became enthusiastic about what was not yet considered a party drug. Favoring the use of cocaine in the treatment of neurasthenia, as an energizer, or as an anesthetic, Freud made a creative and fashionable use of it, heralding practices that our society knows well. Several surprising texts are gathered here on cocaine. Freud recounts the use of coca in history, particularly in South America, from where it was imported. In Cocaine Addiction and Cocaine Phobia, the inventor of psychoanalysis defended coca against its accusers as a dangerous product. Finally, in the letters to Martha Bernays, his future wife, we discover an intimate and loving Freud, telling how he escaped boring dinners thanks to his dear magic substance.Show book

The answers to life's biggest questions can be found by looking at the little things . . . Though you may not be able to see them with the naked eye, parasites—miniscule life forms that live inside other organisms—inhabit our everyday lives. From headlice to bird droppings, litterboxes to unfiltered water, you have brushed up against the most common way of life on our planet. In this unique book, John Janovy Jr., one of the world's preeminent experts on parasites, reveals what can humans learn from the most reviled yet misunderstood animals on Earth: lice, tapeworms, flukes, and maggots that can eat a lizard from the inside, and how these lessons help us negotiate our own complicated world. Whether we're learning to adapt to adverse conditions, accept our own limitations, or process new information in an ever-changing landscape—we can be sure a parasite did it first. At once peculiar and profound, Life Lessons from a Parasite makes a case for using knowledge of the natural world, with all its wonderful mysteries and quirks, to tackle our worst problems.Show book
A hilarious romp through the past, present, and future of Green politics in Canada. "Incisive, frequently hilarious!" - Lean Out with Tara Headley "I burst out loud laughing." - Brian Lilley, Full Comment Podcast "Mark writes candidly and hilariously about the state of Green politics in Canada." - Joseph Planta, TheCommentary.ca "It's great... Some of the details, my god, they make working in that party sound like living in a house of mirrors... Ouch." - Arshy Mann, The Hatchet Mark Leiren-Young, a lifelong environmentalist and Leacock Medal-winning humour writer, journeys to the heart of greenness to reveal the toxic sludge of Canadian eco-politics. For a brief moment in 2019, it looked like Elizabeth May’s Green wave could change Canadian politics and finally wield real power in Ottawa. During that brief moment, Leiren-Young was a campaign manager in a riding the federal Greens were sure to win. He quit on discovering that there was only one thing stopping the Green Party of Canada from changing the country’s electoral landscape forever: the Green Party of Canada. The Greens were not ready for prime time. Or late night. Or four a.m., after last call, when voters stop being picky and are desperate for anyone with a nice smile. Once the spotlight hit, the Greens wilted, never to recover. A comedic take on the sorry state of Canada’s environmental politics, Greener Than Thou explores how the Green party has repeatedly shot itself in the foot, blasted out its kneecaps, and done everything in its power to ensure it will never have a say in decisions that shape the future of our planet.Show book
